Does the B9 support HDMI 2.1 4K 120hz HDR sources ?

coldmorning · November 2019

LG representatives told FlatpanelsHD that the Alpha 7 Gen 2 chipset does not support processing images in 4K 120Hz HDR mode on the LG SM9000 LED TV, only 4K 120hz SDR.

Does this apply to the B9 OLED too as it shares the same hardware ?

To be clear we are not talking about the internal videos apps but external video sources over HDMI 2.1 like say a future Playstation 5 that would output at 4K 120hz HDR.

coldmorning, the B9 does support HDMI 2.1 but the HDR out put would be at 60 hz.

Now I'm back to revive this thread since HDTVTest stated "Despite rumours to the contrary, LG engineers have verbally informed us that the B9 is capable of 4K@120Hz in HDR (especially important for gamers). However, due to the lack of true HDMI 2.1 sources at the moment, there is no way we could verify their claim." and I don't want to make the wrong decision and come to regret it.

Thank you for clearing that up.

@ Tygeezy the Alpha 9 Gen 2 chipset does support 4K 120hz HDR which is whats its the C9, E9 and Z9.

Now it's confirmed the B9 however only supports 4K 60Hz HDR max, if you output at 4K 120hz it will be in SDR only.
